Sintered metal objects from a standard FDM 3D printer

Post by DeltaV »

Filamet(TM) metal-infused filament with Bronze, Copper (soon Brass, Nickel-Silver?) for producing high-density metal objects, sintered in a kiln, after being printed on a cheap, run-of-the-mill FDM printer. Wondering about shrinkage/deformation from heating, but this sounds promising for non-m/billionaires.

Now that is very interesting. Thanks for posting that.

At scales to be at all relevant, say, 12" cube width and above, plain old machining is practical and cheap. Porous, sintered messes based on plastics will be dimensionally unstable and a horror show under vacuum.

How does this compare to lost-PLA metal casting? I'm guessing not nearly as good.
